Definitions

  • the present invention relates to an improved tap welded to a ball valve for very corrosive fluids.
  • the ball valve which can be oriented by means of a drive shaft secured to the valve operating handle, resiliently rests on two opposite seats carried by the connection sleeves of the valve to the fluid inlet and outlet pipes, the angular displacement of the plug allowing alternately to close these sleeves by preventing the flow of fluid through the valve thus closed, or, on the contrary, to put these two sleeves in communication through the valve and, depending on the degree of opening of the valve which depends on the orientation given to the valve, to adjust the flow of fluid passing through the valve.
  • each of these seats by a ring of plastic material serving as a seat for the plug and mounted against the front part of the corresponding sleeve.
  • This seat of plastic material can, in known manner, be mounted by compression between the ball and the sleeves pressed against the concentric exits of the body: either by screwing the sleeves, either by means of bolted stainless steel tie rods, or by welding of these sleeves.
  • the improved tap welded according to the invention overcomes the drawbacks which have just been mentioned, by using a seat holder fixed, preferably by screwing, internally to the body of the tap for adjusting the seat against the ball for sealing. internally and then by welding the connection sleeves to the concentric outlets of the valve body and the seat carrier for external sealing.
  • FIG. 1 The figure is a side view of a tap according to this preferred embodiment of the invention, half outside, half in longitudinal section.
  • the valve comprises a body (1) and an operating block consisting of an operating handle (6) and a drive sleeve (5) of the axis (4) whose base (4 ⁇ ) in hoof, engaged in a groove of the ball valve, allows the rotation of the latter inside the body (1).
  • an annular plastic seat carrier (7) screwed concentrically inside the body (1) of the valve regulates the compression of the seat (8) which ensures the internal seal between the ball valve (3) and the connection sleeve (2), the front cylindrical surface (13) of which is fixed by welding against the front cylindrical surface (11) of the valve body (1), and also against the front cylindrical surface (12) of the seat carrier (7 ) previously screwed, preferably for external sealing.
  • connection sleeves one of which is integral with the body (1) and the other fixed by welding to this same body (1) of the valve, as indicated above, by preventing the flow fluid through the valve in the closed position and vice versa in the open position.
